Indeed, the goal is to raise alarms, not to wash lists. so if you get
few AOL reports, it's ok. but if you get a lot, it means your list is
dirty and you should nuke it.
And AFAIK, AOL FBL requires that the IPs are registered in your name
(whois).

note however that VERP is expensive, not only for the sender but also
for the recipient domain (I prefer if you send a single mail to all my
users...). so use it when appropriate:
- use it in an initial mailing (or when addresses are added to the list)
Then
- use it periodically ("reminder" style mailings)
- use it if you get a bounce ("problem detected, need more infos")
It is recommended to send a confirmation request (COI) before actually
adding an address (so that default is "don't add") and keep evidence
(save the confirmations. so that if a user declares that you spam him,
you can show the confirmations. not a proof, but it helps).
Unfortunately, this is not without problems ("They know I want it, so
why ask again and again?", or "I have no idea what this mail is trying
to tell me. must be a new internet attack. let's delete it now", or "too
busy now. I'll confirm later"...).
so you need to take a decision based on how you acquired the list (in
any case, make it extremely easy to unsubscribe. I personally consider a
web error (sql error blah blah) as a trick to prevent opt-out and
consider the list as having a "fake opt-out process" (well, except if I
can easily find infos about the company showing they are clean...).
